Smart Design
Color: Brushed Nickel, Size: 8.85 inch
Glad I purchased these with the longer tab that hangs over the back of the cabinet door. I feel they are not likely to fall off when pulling towel off the holder. Was surprised that the foam insert did not go all the way along the inside. It is just in front and back. I didn't want the metal part scratching my cabinet door top, so I used self-stick felt pads on the inside top to prevent scratching. A quick solution to prevent possible scratching of the cabinet. Overall, a good purchase for a reasonable price. Does the job, especially when I didn't want to attach a towel rod to the wall.

These towel holders are perfect !
Color: Brushed Nickel, Size: 8.85 inch
These are awesome ! Fit very well on my kitchen cabinet doors. My cabinet doors are beveled a bit at the top so I was concerned these towel holders wouldn’t fit right but they fit great !

good quality
Color: Brushed Nickel, Size: 8.85 inch
i have purchased similar types from other sellers and i think this is by far the best. it goes deeper into the cabinet door therefore does mot fall off and also stays in place, not moving or sliding around. . the others also have broken over time
